part c: do the people surveyed have more dislike for rice than pasta? justify your answer.

No, the people surveyed have not more dislikes for rice than pasta.

Step-by-step explanation:

We are given that a restaurant did a survey among 100 customers to find their food preference .

We have to tell that people surveyed have more dislikes for rice than pasta or not .

Total number of customers=100

The number of customers who liked pasta =30

The number of peoples who liked rice=40

The number of people who liked both pasta and rice =10

The number of people who liked pasta only =30-10=20

The number of people who liked rice only =40-10=30

The number of people who liked rice  are more than pasta.Therefore, the number of people surveyed have more dislike for pasta than rice.

No, the people surveyed have not more dislikes for rice than pasta.
